Advice please,
What is the correct procedure for filling an old 102 (??) with grease , it has two nipples , one just above the other , on the gearbox housing , and another one on the other side , which appears to lubricate the top bush.
Thanks Andy.

Pull the end cap from the gear box & have a look at the contents.
If it's half full of water & the grease looks poor, clean it out & refill with good grease, I use a marine one & use the same stuff on the above water pump bearing nipple.
Replace the end cap & then fill it with the thickest oil you can find, via the nipples I use EP220, fill, till it starts coming out of the bearings, when you run the motor it will then turn into a semi liqued gloop.
These gear boxes were designed to run on liqued grease that is no longer available, and top up as often as possible.
140 oil will tend to run out quite quickly if your bearings have any signs of wear, so you will need something more viscous if you want to keep these beautiful old boxes going.

I cant find a spec. sheet for K70 so a direct comparison isn't possible. How siure are we that K70 is the full type name? Is that from Marston/Seagull literature or correspondance? Anyone got the specs for K70?
When Seagull could no longer get K70 I understand they used stern tube oil.
Castrol Coral Stern Tube Oils
might be of interest.
I wonder if it would be worth asking Castrol's marine division what product available in small quantities is most suitable for replacing K70 in a Seagull gearbox?

I have spoken to people that have seen K70 it was a very black graphitey looking stuff.
Marston's recommended Spirax, I saw in some of the other Charles's paperwork.
Castrol tech support can't find the recipe for K70, I have a friend who works for a grease manufacturer who could get their lab to make up a sample if they could find the recipe.
CharlesP can you post that Marston gear lube paragraph, as I've forgotten exactly what it said.

Ah here we are..
From the 102 operating instructions - 24th edition.
The instructions refer to both oil filler cap types of box and those replenished using an oil gun...
Use best quality gear oil which will pour (original emphasis), NOT grease, from SAE 140 in normal climates to SAE 250 in tropical conditions.
In very cold weather, use heavy engine oil or SAE 90 gear oil, which should be warmed before pouring it into the gearbox.
Avoid grease, however, and use nothing but an oil, a heavy oil.
From the Marston Operating instructions (March 1932)
The propellor shaft and gears are lubricated with thick gear oil or thin grease. The grease recommended is Wakefield's 'Castrolease Light'. This is forced into the bracket by a grease gun supplied in the tool kit.
A grease nipple is fitted on the side of the propellor bracket for this purpose. In cold weather (original italics) it is advisable to use engine oil and the grease mixed in equal parts.
Hope this helps...

I have a booklet from a Seagull dealer here in Holland of about 1960 and it recommends Caltex Outboard Lubricant.
As far as I know a semi liquid grease, used in Seagulls because it mixed up with water and did not become soapy.
Tried to get something like this from my local oil supplier and he offered me liquid grease for ouboards: minimum quantity available 205 ltrs.
I tried to buy this stuff because my THC is leaking lots of oil. But now I use SAE250 from Millers oils and it works as long as the water is not too warm. This winter I will replace the bearings...
